Jane Fonda as a spaced out space girl! No plot, no acting,
no clothes! Altogether not a bad movie!! LOL! B-

From a reviewer at Amazon.com:

Jane Fonda's memorable, zero-gravity striptease during
the opening credits of this 1968 Roger Vadim movie is the
closest the film comes to a liberated marriage of wit and
sex. Based on a French comic strip, the story concerns the
adventures of a 41st-century woman, who pretty much gets
it on with whomever asks. The sci-fi sets were pretty interesting
at the time, though they look rather anachronistic now.
Appreciated today mostly as a camp classic, the movie is
actually more trying than anything else. --Tom Keogh
